WIRELESS BASE STATION DEVICE USING COOPERATIVE HARQ COMMUNICATION SYSTEM, WIRELESS TERMINAL DEVICE, WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD Russian patent published in 2014 - IPC H04W4/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to the technology of a cooperative transmission system which uses a distributed antenna. In a transmission device on a serving eNB side, a first packet transmission unit performs an operation of transmitting a retransmission data packet. On the other hand, in a transmission device on a collaborative eNB side, a second packet transmission unit performs an operation of transmitting a new data packet corresponding to information transmitted from the serving eNB by the packet transmission unit. Control information about transmission to UE by the serving eNB and the collaborative eNB is transmitted using only a PUCCH from the UE to the serving eNB and a PDCCH from the serving eNB to the UE. The serving eNB and the collaborative eNB perform transmission of a new data packet and communication control information etc, through an X2 interface.

EFFECT: efficient HARQ process in a cooperative transmission system.
